I'm developing an application for android 2.3.3. It contains a few EditView's to show an information for an incoming call: country, current time, phone number...

推荐答案

这是不可能的。根据<一href="https://github.com/CyanogenMod/android_packages_apps_Phone/blob/ics/src/com/android/phone/PhoneApp.java#L658"相对=nofollow> PhoneApp 的用于启动InCallScreen被绑定到phoneapp的意图，你就没有机会拦截此。因此，屏幕上会显示每一次来。

It's not possible. According to the PhoneApp the intent used to start the InCallScreen is bound to the phoneapp, you have no chance to intercept this. So the screen will be shown every time.

你可能尝试做的是由 TelephonyManager 当手机进入 CALL_STATE_RINGING 状态，然后画你的UI刚过InCallScreen。也许可以这样做，但你woudn't能够摘机通话（不确定，但我不这么认为），从你的用户界面。也状态未设置时立即InCallScreen弹出，它延迟了一些毫秒。

What you may try to do is to be notified by the TelephonyManager when the phone goes into the CALL_STATE_RINGING state and then paint your UI just over the InCallScreen. It may be possible to do so but you woudn't be able to offhook the call (unsure, but I don't think so) from your UI. Also the state is not set immediately when the InCallScreen pops up, it's delayed by some milliseconds.
